Description

Technical Field

[0001] This utility model relates to the field of door and window profile technology, and in particular to a door and window profile sealing structure. Background Technology

[0002] Window and door profiles are frame materials with specific functional structures, manufactured through an extrusion process according to precise design requirements. They are not only the support structure of windows and doors, but also the most critical component that determines their performance (such as heat insulation, sound insulation, waterproofing, and wind pressure resistance), service life, and appearance.

[0003] Chinese Patent No. CN218407136U discloses a sealing structure for aluminum profile doors and windows. The key technical points are: an aluminum profile window frame, glass installed inside the aluminum profile window frame, an installation groove inside the aluminum profile window frame, and the glass fixedly installed in the installation groove; a sealing component, disposed on the bottom surface of the aluminum profile window frame, used to seal the aluminum profile doors and windows. The sealing component includes two injection grooves, respectively located on the top and bottom surfaces inside the aluminum profile window frame. Several outflow holes are provided on one side of the injection grooves. Through the coordinated use of the aluminum profile window frame, glass, installation groove, injection groove, outflow hole, connecting groove, flow groove, sealing hole, guide plate, limiting groove, injection hole, horizontal flow groove, and connecting hole, the sealant and glass glue can provide a double seal for the aluminum profile doors and windows, thereby improving the sealing effect of the aluminum profile doors and windows.

[0004] However, the above-mentioned technical solutions use a combination of sealant and glass glue to achieve double sealing. Although this method improves the overall sealing performance to some extent, there are still obvious limitations due to the unavoidable assembly gaps between the glass and the profile. Specifically, due to the influence of operating procedures, environmental conditions, and the material's own characteristics during construction, it is often difficult to achieve uniformity and continuity in filling. Localized uneven thickness, internal cavities, or poor adhesion may occur. When the window glass is subjected to external vibrations and impacts, such as shaking caused by wind, vibrations during opening and closing, or structural vibrations from the surrounding environment, stress concentration can easily occur in these poorly filled areas, leading to peeling, cracking, or loosening between the sealant and the glass or profile interface. Over time, the sealing performance gradually declines, potentially resulting in airtightness loss, water leakage, and reduced sound insulation, seriously affecting the durability and functionality of the window system. Utility Model Content

[0005] Based on the existing technical problems of uneven thickness, internal cavities, or loose bonding in the sealing of door and window profiles, peeling, cracking, or loosening between the colloid and the glass or profile interface, the sealing performance gradually declines over time, which may lead to loss of air tightness, water leakage, and reduced sound insulation. This utility model proposes a sealing structure for door and window profiles.

[0006] This utility model proposes a door and window profile sealing structure, including horizontal aluminum materials and vertical aluminum materials. The two ends of the two sets of horizontal aluminum materials and the two ends of the two sets of vertical aluminum materials are fixedly installed to form a door and window profile. A sealing device is provided inside the door and window profile. The sealing device includes a sealing elastic membrane, which seals the gap between the door and window profile and the glass.

[0007] Preferably, the sealing device further includes a slot, which is fixedly installed on the inner wall of the door and window profile, and a storage groove is slidably inserted into the inner wall of the slot.

[0008] Through the above technical solution, in order to facilitate the storage of sealant or expanding adhesive, by delivering sealant into the storage tank, the sealing elastic membrane can expand, allowing the sealing elastic membrane to contact the glass and seal the gap between the glass and the door and window profiles. At the same time, the storage tank and the card slot are slidably connected, which facilitates the installation, disassembly and replacement of the storage tank.

[0009] Preferably, the outer surface of the storage tank is fixedly connected to the outer surface of the sealing elastic membrane, and the sealing elastic membrane is made of rubber.

[0010] Through the above technical solution, the sealing elastic membrane made of rubber can expand, which facilitates the expansion of the sealing elastic membrane to adhere to the glass, thereby adapting to the outer surface of the glass.

[0011] Preferably, the inner wall of the door and window profile is fixedly installed with a retaining strip, and two retaining strips are distributed on both sides of the glass.

[0012] The above technical solution allows the glass to be limited by the locking strip, facilitating glass installation.

[0013] Preferably, overflow holes are provided on the outer surface of the door and window profile, the outer surface of the card slot, and the outer surface of the storage slot, and multiple overflow holes are located on the same axis.

[0014] The above technical solution allows for easy observation of the sealant filling through the overflow hole, thereby revealing the expansion of the internal sealing elastic membrane.

[0015] Preferably, the outer surface of the door and window profile, the outer surface of the card slot, and the outer surface of the storage slot are all provided with input holes, and a sealing plug is slidably inserted into the inner wall of the input hole.

[0016] Through the above technical solution, sealant can be delivered into the storage tank through the input hole, and the sealing plug can seal the input hole.

[0017] Preferably, a sealing strip is slidably inserted into the inner wall of the door and window profile, and the outer surface of the sealing strip and the outer surface of the door and window profile are coated with a glass glue coating.

[0018] The above technical solution involves first sealing the door and window profiles and glass with a sealing strip, creating multiple seals, and then sealing the sealing strip again with a glass glue coating. This multiple sealing makes the seal between the glass and the door and window profiles more secure.

[0019] The beneficial effects of this utility model are as follows:

[0020] By incorporating a sealing device, a seal can be achieved between the window and door profiles and the glass. The rubber-made sealing elastic membrane can expand, allowing it to adhere to the glass after expansion and adapt to the glass's outer surface. An overflow hole allows for observation of the sealant filling and the expansion of the internal sealing elastic membrane. By first sealing the window and door profiles with a sealing strip, creating multiple seals, and then sealing the sealing strip again with a glass adhesive coating, the multiple seals ensure a more robust seal between the glass and the window and door profiles. This solves the technical problems of existing window and door profile seals, such as uneven thickness, internal cavities, or poor adhesion, peeling, cracking, or loosening at the interface between the adhesive and the glass or profile. Over time, the sealing performance gradually declines, potentially leading to airtightness loss, water leakage, and reduced sound insulation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-6 A door and window profile sealing structure includes horizontal aluminum members and vertical aluminum members. The two ends of the two sets of horizontal aluminum members and the two ends of the two sets of vertical aluminum members are fixedly installed to form a door and window profile 1. A sealing device is provided inside the door and window profile 1. The sealing device includes a sealing elastic membrane 22, which seals the gap between the door and window profile 1 and the glass.

[0030] Specifically, in order to facilitate the expansion of the sealing elastic membrane 22, the sealing device also includes a slot 2, which is fixedly installed on the inner wall of the door and window profile 1. A storage groove 21 is slidably inserted into the inner wall of the slot 2. In order to facilitate the storage of sealant or expanding adhesive, by delivering sealant into the storage groove 21, the sealing elastic membrane 22 can be expanded, so that the sealing elastic membrane 22 comes into contact with the glass and seals the gap between the glass and the door and window profile 1. At the same time, the storage groove 21 and the slot 2 are slidably inserted, which facilitates the installation, disassembly and replacement of the storage groove 21.

[0031] Specifically, the outer surface of the storage tank 21 is fixedly connected to the outer surface of the sealing elastic membrane 22, which is made of rubber. The sealing elastic membrane 22, made of rubber, can expand, so that it can fit the glass after expansion and thus adapt to the outer surface of the glass.

[0032] Specifically, in order to limit and position the glass, a retaining strip 23 is fixedly installed on the inner wall of the door and window profile 1, with two retaining strips 23 distributed on both sides of the glass; the retaining strips 23 can limit the glass and facilitate the installation of the glass.

[0033] Specifically, in order to facilitate observation of the expansion effect of the sealing elastic membrane 22, overflow holes 24 are provided on the outer surface of the door and window profile 1, the outer surface of the slot 2, and the outer surface of the storage slot 21. Multiple overflow holes 24 are located on the same axis. The overflow holes 24 facilitate observation of the sealant filling, thereby obtaining the expansion of the internal sealing elastic membrane 22 and preventing excessive injection of sealant.

[0034] Specifically, an input hole 25 is provided on the outer surface of the door and window profile 1, the outer surface of the slot 2, and the outer surface of the storage slot 21. A sealing plug 26 is slidably inserted into the inner wall of the input hole 25. Sealing glue can be delivered into the storage slot 21 through the input hole 25, and the sealing plug 26 can seal the input hole 25.

[0035] Specifically, a sealing strip 3 is slidably inserted into the inner wall of the door and window profile 1, and the outer surface of the sealing strip 3 and the outer surface of the door and window profile 1 are coated with a glass glue coating 31. By first sealing the door and window profile 1 and the glass with the sealing strip 3, multiple seals are achieved, and then the sealing strip 3 is sealed again with the glass glue coating 31. The multiple seals make the seal between the glass and the door and window profile 1 more secure.

[0036] By setting a sealing device, a seal can be formed between the window / door profile 1 and the glass. The rubber-made sealing elastic membrane 22 can expand, allowing it to adhere to the glass after expansion and adapt to the outer surface of the glass. The overflow hole 24 allows for observation of the sealant filling and thus the expansion of the internal sealing elastic membrane 22. By first sealing the window / door profile 1 and the glass with the sealing strip 3, multiple seals are formed, and then the sealing strip 3 is sealed again with the glass glue coating 31. This multiple sealing makes the seal between the glass and the window / door profile 1 more secure. This solves the technical problems of uneven thickness, internal cavities, or poor adhesion in the existing window / door profile 1 seal, as well as peeling, cracking, or loosening between the glue and the glass or profile interface. Over time, the sealing performance gradually declines, which may lead to loss of air tightness, water leakage, and reduced sound insulation.

[0037] Working principle: Insert the storage slot 21 into the slot 2. After splicing one horizontal aluminum member and two vertical aluminum members, insert the stripper into the slot 23. Then install the other horizontal aluminum member to form the door and window profile 1. After injecting sealant into the inlet hole 25, the sealant enters the storage slot 21 and causes the sealing elastic membrane 22 to expand and contact the glass to seal the gap between the glass and the door and window profile 1. Observe the sealant injection through the overflow hole 24. After the sealant overflows through the overflow hole 24, the injection can be stopped. Seal the inlet hole 25 through the sealing plug 26.

[0038] The sealing strip 3 is inserted into the gap between the glass and the door / window profile 1, and then a glass glue coating 31 is applied.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
